Jamaica shares same earthquake faultline as Haiti

KINGSTON, Jamaica (JIS) -- Jamaica shares the same faultline (a crack or break in the earth's surface) with Haiti, which suffered a devastating 7.0 magnitude earthquake on January 11.

This was disclosed by the Head of the Earthquake Unit of the University of the West Indies (UWI), Dr Lyndon Brown, at a JIS Think Tank in Kingston on Wednesday.

"The fault that created the quake in Haiti runs right across the western end of the Dominican Republic, through Haiti, cuts across the Caribbean Sea into Jamaica and continues more or less into different fault lines across Jamaica: one continuous fault line runs across from Haiti to Jamaica," Dr Brown stated.

He added that the activities in the region, following the Haiti earthquake, are not unusual, at this time.

"A number of aftershocks have taken place, and this is quite natural. The aftershocks will be more continuous after the large earthquake, but then this will die down and become less frequent," he said.

Aftershocks, such as the magnitude 6.1 tremor that occurred in Haiti again on the Wednesday morning (January 20), can be large but will become less frequent over time.

He said, however, that the other earthquakes that have taken place in Guatemala, Venezuela, and El Salvador are happening on the Pacific Plate fault line, which is not the same one on which Haiti and Jamaica is located.

"Right now we do not see the association between the events," he added.

He said that while studies are being done by an American researcher, to see the relationships between the fault lines, none has so far been established, and what is happening is that stresses are being naturally released along respective fault lines.

"Earthquakes are very, very, common. If you look at a map of Jamaica you will see that last year we had about eight felt events (earthquakes) and about 200 that were weak but could just be picked up as earthquakes," he said.

He stated that, on average, there have been about16 earthquakes on an annual basis that are greater that magnitude 7.0 , about 120 around magnitude 6.0 and an innumerable amount at magnitude 5.0 and below.

"What is happening in the region is very interesting. Earthquakes are natural events that happen when stresses that have built up along fault lines are released, creating elastic waves that generate convolutions on the face of the earth," Dr Brown said.

He added that the destruction wrought by an earthquake is dependent on the location and strength of a building, as well as the strength of the earthquake.

Haiti rejects Dominican Republic troops

By Louis Charbonneau:


UNITED NATIONS (Reuters) -- Earthquake-ravaged Haiti turned down an offer of troops from the neighbouring Dominican Republic, forcing the United Nations to look elsewhere for additional peacekeepers, UN diplomats said on Wednesday.

The Dominican Republic had offered an 800-strong battalion to form part of the reinforcement of the UN peacekeeping mission in Haiti.

"We understand the Haitian government has said no to them," one Western diplomat said on condition of anonymity. He said he assumed the decision came from Haitian President Rene Preval.

The two states share the Caribbean island of Hispaniola but have a history of tense relations.

A UN official confirmed that Haiti turned down the offer but said the decision might not be definitive and talks were under way to see if Haiti would allow a rescue team or police from the Dominican Republic to help with the relief efforts.

"We're hoping other countries can provide troops," the official said.

The full potential strength of the UN peacekeeping force is now 12,651, up from the current level of around 9,000, after a UN Security Council resolution adopted on Tuesday.

The United Nations is now rushing to find the extra 3,651 troops and police to help maintain security and deliver aid.

Edmond Mulet, sent to Haiti to take over the UN force after its chief, Hedi Annabi, and dozens of other UN staff died in the earthquake, has said that Brazil was offering more troops and France and Chile were offering police.

UN officials have said the Philippines might also top up its existing contingent.

Haitian officials say the death toll from the Jan. 12 quake was likely to be between 100,000 and 200,000, and that 75,000 bodies had already been buried in mass graves.

The United States has around 12,000 military personnel in Haiti, on ships offshore or en route. They are not under UN command, though they are cooperating with the United Nations, which is overseeing the relief effort.
